What are the network security requirements for information security compliance?

Network security requirements for information security compliance typically include several key aspects to ensure data protection, system integrity, and regulatory adherence. These requirements may vary based on industry standards (e.g., GDPR, HIPAA, PCI-DSS) but generally cover the following:

  1. Data Encryption: Sensitive data must be encrypted both in transit and at rest. For example, using TLS/SSL for data transmission and AES-256 for stored data.

    • Example: A financial institution encrypts customer payment data during online transactions and stores it in an encrypted database.

  2. Access Control: Implement strict access management, including multi-factor authentication (MFA), role-based access control (RBAC), and least privilege principles.

    • Example: A healthcare provider restricts access to patient records based on employee roles, requiring MFA for login.

  3. Network Segmentation: Isolate critical systems from less secure networks to limit attack surfaces.

    • Example: An e-commerce platform separates its payment processing servers from public-facing web servers using VLANs or firewalls.

  4. Intrusion Detection and Prevention (IDPS): Deploy systems to monitor and block malicious activities in real time.

    • Example: A company uses an IDPS to detect and mitigate DDoS attacks on its web servers.

  5. Regular Security Audits and Patch Management: Conduct vulnerability assessments and apply patches promptly to fix known security flaws.

    • Example: An enterprise schedules quarterly penetration tests and updates its software to address CVEs.

  6. Incident Response Plan: Establish a documented process to detect, respond to, and recover from security incidents.

    • Example: A cloud service provider has a predefined incident response team and escalation procedures for data breaches.

For cloud environments, Tencent Cloud offers services like Tencent Cloud Web Application Firewall (WAF) to block SQL injection and XSS attacks, Tencent Cloud SSL Certificates for encryption, and Tencent Cloud Security Center for real-time threat detection and compliance checks. These tools help meet network security requirements efficiently.
